Absolutely amazing, the dot is great and the 2 intensity settings keep my battery from going low. Really easy to install on a 98 custom, took about 5 minutes straight out of the box. Also the paintball warrantee is good

Weaknesses:

not as easy to adjust as some sights, need a phillips head screwdriver

Conclusion:

This sight is awsome and is really good for players who do more than "Spray and Pray"
